The Ravens were unwilling to pay Boldin the $6 million he was due next season, and Boldin was unwilling to agree to a pay cut after helping the Ravens win a Super Bowl. Boldin was stellar during the playoffs with 22 catches for 380 yards and four touchdowns. Now, Boldin will join the team the Ravens defeated in the Super Bowl, teaming with wide receiver Michael Crabtree and tight end Vernon Davis to immediately upgrade the 49ers’ receiving corps.

Ravens quarterback Joe Flacco and other teammates were hoping Boldin could work out a deal to stay in Baltimore. Instead, Boldin will play for Jim Harbaugh in San Francisco, after playing for John Harbaugh with the Ravens. Stunning movement already in the NFL, with free agency set to begin Tuesday.

"Anquan was a great receiver for myself and for our football team," said Flacco, who signed a six-year, $120.6 million deal with the Ravens last week. "It's sad to see a guy like that go, but at the same time you want what's best for him and you just wish him the best of luck.

"Anquan was a big part of this football team, a big part of this offense. He's one of the many reasons we won the Super Bowl this year."
